Abstract

Background. For each farm, which is engaged in the reproduction of pigs, regardless of it's pedigree or commercial, quality repairs and livestock rearing is one of the most important tasks for the improvement of animal productivity and profitability of the herd. As practice shows, it is normal for the age structure of the herds from farms every year because of decay and other causes is eliminated 25–30% (large pig farms up to 40%) of the principal boars and sows. Instead of retiring, in the main herd's young, proven pigs and boars. Important is the question of growth and development of young pigs, because it is impossible to expect a high level of performance and good development of the piglets from sows that have low live weight and had not completed its development and is physiologically capable of effectively spironolatone, to produce milk and raise pigs. Objective. The aim of the research was to determine the growth and development of young pigs of large white breed in the farm “Agromir” Nikopol district Dnipropetrovsk region. Methods. For the experiment was formed by a group of gilts of large white breed in the amount of 65 goals. Studied indicators of growth for the dynamics of live weight at 2, 4 and 6 months, and the average relative and absolute increases in the main periods of growth. Sows first farrowing examined productive characteristics on the following parameters: prolificacy (goals), the weight of the nest at birth (kg), weight of the nest at weaning (kg). Results. Indicators live weight of gilts at the age of 2, 4 and 6 months correspond to their age in the main periods of growth and respectively of 17.5±0.22 kg, 45.6±0.41 and 82.8±0.76. This indicates a good overall development and the formation of animals of the desired type. Average daily gains of pigs made 468.3±0.17 g to 620.0±0.11 g. The data show that the highest absolute body weight gain was observed in pigs in the period from birth to 6 months of age and was 81.7±1.12 kg. In other periods of the cultivation, the figure was 16.4±0.85 kg in the period from birth to 60 days of age and 37.2±0.96 kg in the period from 4 to 6 months of age. Analyzing the data of relative growth, we can conclude that in the period from birth to 60 days of age and in the period from birth to 6 months of age, the figure was 176.3±2.76% 194.8±5.77%, respectively. Found that average 65 goals prolificacy of sows is 10.75±0.981 piglets, weight of the nest at birth – 12.8±2.47 kg, the weight of the nest at weaning – 212.8±10.63 kg. Conclusion. It can be concluded that cultivation of healthy gilts is a key element in the organization of the technological process of reproduction and production of pork. This accumulation of internal reserve, which contributes to the increase of profitability of pork production in the farm “Agromir” Nikopol district Dnipropetrovsk region.
